Section 75(4) of the GST regime requires that an opportunity of hearing be granted upon receipt of a request; failure to afford a personal hearing renders the impugned action procedurally infirm and susceptible to challenge.

The practical effect is that absence of procedural hearing and an ineffective alternative remedy justifies setting aside the impugned administrative order.
